Top critical review
Not sure if mine are defective, unable to handle use in a flashlight, or what.

I waited to write this review until I tested these out for a while.
The flashlight I have been testing them in is a SOG Dark Energy DE-01, using a single CR123A battery. They get expensive if you use these type of batteries a lot, so I looked into rechargeable options. I had two OLight 650mH RCR123As that recharged well, and had good life, but I misplaced them, and decided to give a pack of these a try.
At first I was optimistic, they seemed a solid replacement. It's hard to find rechargeable RCR123A batteries. I noticed they had a really short battery life however. I've seem some CR123As dim when they were starting to lose power, but these went totally dark (maybe it's a rechargeable thing, I can't remember from my old Olight ones), after a MUCH shorter period of time. I tested all four of my batteries, using them until they died, recharging, seeing if maybe they needed a "break in period". No such luck. I'm going to time the life of them at full power compared to a full charge from a name brand regular CR123A, and may update this post when I do so.
I had no idea what Arlo anything was when I bought these, now I do, but according to all the specs and reviews, they should make good rechargable batteries for my lights. These are awful. I'm going to see if I can source the Olight ones again, maybe risk trying another brand on here, but I'm extremely hesitant to try any more of these. Maybe your experience is different, but these were a huge disappointment for me, even if I'll use them for their very limited purpose just to save money.
EDIT: 30 minutes, and the battery starts turning on and off, and then stays off.
